The saga continues ...  They did completely revise everything and the code is "finished" as far as they can do. Was hoping yours would be part of the cure. That Lenovo if I remember correctly had a weird battery arrangement where the battery and "power" part of the ACPI only showed up when it was running on battery but not AC if this is the one I remember. So there's something squirrely to it, that much I *do* remember. Just for laughs and giggles, try grabbing a terminal (Applications->Accessories->Terminal) and try this command: shutdown -p now The above SHOULD shut down your machine. If it doesn't then it's definitely power ACPI problems in that some part of the hardware is NOT shutting down. Hopefully something will show on the black screen indicating that it tried. Is this the machine you sent me the diags for with that NVIDIA MCP55 chipset? The guys said tha NVidia never did respond to their request for technicals on them ... |

That command did not shut down the laptop, however the response was:
" shutdown: NOT super-user " so I tried su shutdown -p now
and the response was:
" su: Sorry "
and then tried sudo shutdown -p now
and the response was:
" bash: sudo: command not found "
Sooooo, I don't know if its because I'm not "super-user" , or if its the power ACPI
problem you were looking for.....

Just did a gedit search on the diags for the laptop, and there were no NVIDIA hits.
Did the same for the desktop, and it is the desktop that has the NVIDIA MCP55 chipset.
So that may be a cause for the desktops quirkiness, but it is not part of the
laptop neurosis........

For the heck of it I just tried "shutdown -p now" on the desktop, and it gives the
same response:
""[KNOS@KNOS-64bit ~]$ shutdown -p now
shutdown: NOT super-user
[KNOS@KNOS-64bit ~]$
""
so I get the same reponse from both machines.

One slight change with RC1: the battery icon now shows when its on a/c, BUT it shows it as
completely discharged (red-empty).

My fault there ... forgot to tell you to type in su in the first terminal and then try that shutdown-p now in the second prompt. The reason for trying it this way is that the shutdown command from the menu depends on the computer's "ACPI-power" hardware and that's apparently not working on yours. The shutdown command from the terminal is a bit more aggressive, and the reason why I'm asking is that if that takes it down and the ACPI one doesn't, then it's definitely an ACPI problem whereas if neither works, then it's a hardware problem. Just trying to figure out which. |

One slight change with RC1: the battery icon now shows when its on a/c, BUT it shows it as completely discharged (red-empty). Yep ... that definitely tells me that the ACPI power part of that machine's BIOS is "not ta' home" since KNOS is receiving a value of zero for the voltage when it's querying it. That the icon appears means that we ARE communicating with it, but it's not answering. Just for laughs and giggles, try that with the AC power disconnected for a bootup and see if the battery shows up AND perhaps, it might even shut down. If shutdown works as well as the battery shows up, then it's definitely that issue I was told about with a handful of those Lenovos in that the battery and power circuit (and its monitoring) do not work when on AC power ... that would answer ALL of the questions here ... |

That made the command work, but....
it did not go any further than the System>Shutdown command
from the menu.

With a/c disconnected, the icon now shows the battery almost full.
But, Lenovo laptop still doesn't shut all the way down either by
menu or by terminal shutdown method.
Would a diags from battery power be of any use?

"" With a/c disconnected, the icon now shows the battery almost full. But, Lenovo laptop still doesn't shut all the way down either by menu or by terminal shutdown method. Would a diags from battery power be of any use? Sorry to say, that gives us the answer ... it's the hardware and it's different from the standard "ACPI_IBM" standards that Lenovo always used. While the shutdown button in the desktop only does an acpi shutdown, that console method tries all three possibilities - acpi first, then soft bios reset and finally hard bios reset. If none of them worked, then the hardware just isn't listening meaning that the only way that machine will shut down is the power off switch held down long enough for the power supply to comply. Wish I had a happier answer, but the kernel guys did all they can. :( |

Which Lenovo laptop is having this problem?
My Lenovo T61 has not shown any of these problems with KNOS.

Which Lenovo laptop is having this problem? My Lenovo T61 has not shown any of these problems with KNOS. I think it was a T60 ... it's been a while so I forget. We've had numerous other folks with Lenovos and same situation, no problem with any of this. The one in question though has a really weird battery/charging configuration and an unusual BIOS power control and I think it was limited to that one model based on all the other Lenovos we've seen working just fine. Still want to see it get solved, but that's one for the BSD ACPI team to do. |

I finally uncovered the receipt for it -
it is the Lenovo 3000 C200 laptop w/
Intel celeron M420 1.6GHz
